End of the quarter is soon and I'm dying in quarentine!! Increasing the air temperature inside a hot air balloon makes it lighter than the surrounding air, so the balloon can lift up. The density of hot air is about 0.5kg/m3. less than that of cool air, which means a cubic meter of hot air can lift about 0.25kg. What is the minimum volume of hot air needed to lift a hot air balloon carrying 500kg

Hi there! Hopefully this helps!

The volume of air = 2000 m³

Explanation:

We are given that 1 m³ of hot air can lift a mass of about 0.25 kg.

To find the volume of hot air required to lift a mass of 500 kg, we will use cross-multiplication as follows:

1 m³ > 0.25 kg

?? >500 kg

volume of hot air required = (500*1) / (0.25)

volume of hot air required =  2000 m³

step-by-step explanation:

1. minimum

2. 6400

3. eight

hope this !
